Problems solved by technology

Starting in mid summer and continuing through the fall the chance of serious fires is high since spring growth caused by winter rain is dry and there is virtually no precipitation during the summer months.
During the summer and fall, when a scrub brush or forest fire starts it will generally spread rapidly and is extremely difficult or impossible to control.
The result can be a lose of forest and houses and buildings surrounding the area where the fire is burning.
During a typical fire season in Southern California damages to property can cost be as high as a billion dollars or more.
When the rain finally arrives in December and January the ground is often barren of vegetation w

Embodiment Construction

[0021] Referring to FIG. 1, there is shown a block diagram of a fire fighting system 10 which is used to fight forest and brush fires under hot, winding and dry conditions. A blower / fan 14 moves air 12 from the atmosphere through the fan housing exiting the housing at extremely high speeds, e.g. between 100 and 400 mph. Cold water 16 is then pumped into the resultant air flow generating particles of water. The temperature range of the water is generally in the range of 40 to 50 degrees fahrenheit. A filter / screen mesh 18 may be used to generate very fine particles of water in the order of several microns, e.g. 1-40 microns.

[0022] Particle size cold water droplets 20 are driven into the atmosphere 22 which drops the temperature considerably at the edge of the fire creating a barrier against the fire. This, in turn, prevents the fire from spreading and the resulting heat loss will extinguish or put out the fire.

[0023] The fan 14 may be any conventional centrifugal machine which draw...

Abstract

A fire fighting system for fighting forest and brush fires under dry, hot and windy conditions which includes a jet engine for generating a high speed air stream, a water source for supplying water to a cooling system which lowers the water temperature to between forty and fifty degrees fahrenheit, a nozzle for injecting cold water into the air steam and a filter which provides very fine particles of cold water within the stream. The stream of cold water is directed to a forest or brush fire dropping the temperature of the fire which eventually extinguishes the fire.

Description

[0001] This application is a continuation in part of U.S. patent application Ser. No. 11 / 094,547, filed Mar. 22, 2005.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to fire fighting systems and equipment. More specifically, the present invention relates to a jet engine blower type fire fighting system which generates high velocity liquid cooled air streams at a constant temperature and velocity that are very useful in fighting forest and other types of fire. [0004] 2. Description of the Prior Art [0005] Forest and grass land fires in the western states including California are a constant concern because of the lack of moisture, the extremely short raining season, the high winds and the long hot summers. Starting in mid summer and continuing through the fall the chance of serious fires is high since spring growth caused by winter rain is dry and there is virtually no precipitation during the summer months. During the summer...
